AT TORbIEY DYNAMOELECTRIC MACHINE ASSEMBLY BACKGROUND OF THE INVENTIONThis invention relates generally to dynamoelectric machine mountingarrangements and, more particularly, to arrangements that facilitatesupporting a dynamoelectric machine having a first configuration, e.g.,a housing of a first size, by means of a mounting member that isparticularly adapted to support a dynamoelectric machine of a second,different configuration or size.

Numerous types of mounting arrangements have been used heretofore forsecuring dynamoelectric machines, e.g., motors, to supporting structuresin a desired position relative to means driven by such motors. Generalapproaches followed, heretofore, have included the use of axiallyprojecting mounting studs;

motor supports in the form of cradle type bases; and band type mounts inthe form of hoop or ring-shaped flat straps or hoop or ring-shapedwires.

As will be understood, band mounts have been used by equipmentmanufacturers to support different types of motors indrivingrelationship with diverse types of apparatus, e.g., appliances and airmoving equipment. In many instances, the band mounts themselves havebeen provided from one source and motors having a desired performancerating have been provided from another source. In at least some of thesecases, the structural details of a selected band mount has not beenconfigured to properly support all of the different motor models capableof meeting or exceeding the desired performance rating. This of coursereduces the options available to a manufacturer with regard to selectingcommercially available motors for use with that manufacturers equipment.

For example, in those cases where two or more different motor modelswould each meet desired perforinance standards but each have differentnominal outer diameters;'the selection of a specific band mount having amotor mounting diameter corresponding to only a specific one of suchmotorshas heretofore effectively prevented the use of all but thatspecific one of the motors. Accordingly, it would be desirable toprovide means that would permit the utilization of one or moredifferently sizedor configured motors with equipment that is suppliedwith band type mounts that are not particularly designed to support suchdifferently sized motors. Moreover, it would be desirable that suchmeans facilitate field replacement of band mounted motors of a firstnominal physical size with motors of a different nominalsize. Theprovision of such means would be particularly desirable in thoseapplications wherein motors having desired performance characteristicsare available in smaller physical sizes than heretofore; or wherechanges in equipment applications now permit the use of smaller motors.

While one approach to the utilization of differently sized motors byoriginal equipment manufacturers would be to redesign the equipmentand/or motor mounting means was to accommodate such motors,

this approach would not completely solve the problem and variouspractical considerations have discouraged this approach. For example,the actual size of competitively rated motors may still vary from onemotor manufacturer to another. In addition, the redesign and retoolingexpense that would be involved in changing mounting arrangements may beprohibitive to relatively small equipment manufacturers. Furthermore, a

change in equipment design or mounting hardware would reduce the easewith which a manufacturers equipment already in the field could berepaired by in terchanging parts currently used by the manufacturer.Thus, any changes in the physical sizes of parts (including, forexample, motors) or mounting arrangements for a given type of equipment,would more desirably be such that parts used both currently andheretofore in the manufacture of such type of equipment may also be usedas replacement parts for the same type of equipment in the field.

It will thus be understood that it would be desirable to providemounting adapter means for dynamoelectric machine and assemblies ormounting arrangements including the same for mutually accommodating amounting member of a first nominal configuration and a dynamoelectricmachine of a different nominal configuration. Furthermore, it would bedesirable, if not necessary, that such adapter means satisfactorilywithstand mounting and holding forces applied to the dynamoelectricmachine so that a stable and reliable mounting arrangement will result;and that such adapter means be readily assembled with a dynamoelectricmachine so supported, and yet resist inadvertent disassembly.

SUMMARY OF THE INVENTION Accordingly, it is an object of the presentinvention to provide means for use in mounting dynamoelectric machineswhereby driven or driving dynamoelectric machines having first nominalconfigurations may be reliably supported by mounting structure havingdifferent nominal configurations.

Other objects of the present invention are to provide assemblies orarrangements of dynamoelectric machines and adapter means that may besupported in driving or driven relationship to other machine elements ina table and reliable manner.

Briefly, these and other objects are achieved in accordance with oneform of my invention by an im-.

proved arrangement which, in the illustrated embodiment, includes amotor structure having a first predetermined outer peripheralconfiguration (i.e., a nominal outer diameter) with a plurality ofspaced apart openings therein that may be utilized for cooling the motorduring operation thereof; and adapter means for augmenting theperipheral configuration of the motor. In the illustrated embodiments,the adapter means comprise a plurality of spaced apart clips, e.g.,spacer clips, that are fastened to the shell or casing of a motoradjacent to at least two spaced apart coolant passages formed therein.In a preferred form, the clips are fabricated of a material that may beresiliently deflected during assembly with a motor so as to facilitatesuch assembly and yet provide a reliable arrangement that facilitatesmounting the motor in a desired environment in a stable manner. Inpreferred forms, the clips resist undesirable distortion or deformationthereof during mounting of the motor assembly and thereby contribute tostable mounting arrangements. In preferred exemplifications, the clipsare fabricated by stamping clip blanks from a strip of sheet materialand then forming the stamped blanks to a desired clip configuration.Thereafter, the clips may be readily assembled with motors or otherdynamoelectric machines.

The subject matter which I regard as my invention is particularlypointed out and distinctly claimed in the concluding portion of thisspecification. The invention, itself, however, both as to itsorganization and method operation, together with further objects andadvantages thereof, may be better understood by reference to thefollowing description taken in connection with the accompanying drawing.

BRIEF DESCRIPTION OF THE DRAWING In the drawing:

FIG. 1 is a perspective view, with parts broken away, of an assembly ofa motor and mounting adapter means, embodying the present invention inone form, supported by a band type mount;

FIG. 2 is a perspective view (with parts broken away) of part of theassembly shown in solid lines in FIG. 1, and illustrates one method ofassembling adapter means in the form of a clip to the motor of FIG. 1;

FIG. 3 is a stamped blank from which the clip of FIG. 2 may be formed;

FIG. 4 is a perspective view of another form of clip that is shown inphantom in FIG. 1; and

FIG. 5 is a blank from which the clip of FIG. 4 may be formed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Turning now to the drawings andparticularly to FIG. 1, I have illustrated one form of the presentinvention incorporated in an arrangement that includes a motor having ahousing that includes a shell !14 and a pair of'end frames 12, 13disposed about a wound stator core. The end frame portions of thehousing support suitable bearing means that rotatably support the shaft15 of a not shown rotor. Since a description of the overall constructiondetails of the motor 10, including the parts within the housing, is notnecessary to an understanding of the invention, further description isnot presented herein.

With continued reference to FIG. 1, the outer peripheral surface portionof the motor, i.e., the shell 14 is provided with a plurality of spacedapart openings 16 with a row of openings being generally adjacent to oneend 17 of the shell and another row of openings being located generallyadjacent to the end 18 of the shell. In addition, openings 19 arepreferably provided in at least one of the end frames. During operationof the motor 10, a flow of a cooling medium, e.g., air or other coolant,through these openings may be used to advantage to cool-the windings andat least part of the bearingsystem of the motor 10. This cooling benefitmay be obtained of course whether the motor is of dual or unit bearingdesign; whether the motor utilizes shading coils or distributedauxiliary windings during starting; and whether or not one or morecapacitors are connected in circuit with the energization windings ofthe motor.

Also included is mounting structure that may be a member in the form ofthe strap 21. The strap 21 is provided with a plurality of mounting arms22 extending from the strap and fastened thereto in conventional manner,e.g., by welding or other suitable means. Although the arms 22 have beebroken away for clarity in FIG. 1, it will be understood that one ormore arms may be used to fasten the mounting member, i.e., strap 21, toequipment that is to be powered by a motor supported within the strap21. Moreover, the band type mounting member may be a wire hoop ratherthan the illustrated strap 21, as will be understood. Variations of thisgeneral approach are taught, for example, by Staak U.S. Pat. No.2,936,947; Copeland U.S. Pat. No. 2,936,140; Reisch U.S. Pat. No.2,832,554; Doe U.S. Pat. No. 2,467,296; and Seyfried U.S. Pat. No.1,873,343. Of course, the arms 22 may be entirely omitted and the facingends 23, 24 of the strap 21 may be used to clamp the strap to asupporting plate or panel in the equipment or appliance to be powered bythe motor 10. When this approach is followed, the bolt 26 and nut 27 maybe used to secure the strap 21 to the clamped plate or panel.

When following either of these approaches, the nut 27 and bolt 26 orother suitable clamping means are preferably used to securely clamp atleast portions of the inner surface 28 of the strap 21 or other mountingloop forming member against mounting adapter means that will bedescribed in more detail hereinafter. Moreover, in both of the justdescribed approaches, as well as in others, it will be generallydesirable to support the motor 10 relative to the apparatus from which amounting loop is suspended so that the center line of the shaft 16thereof will be positioned in a predetermined manner relative to theloop. For example, it is oftendesirable for the center line of shaft 16(i.e., rotational axis of the motor 10) to at least approximatelycoincide with the center of the mounting opening defined by the interiorclamping surface 28 of the strap 21. For this reason, in the FIG. 1exemplification, the adapter means are provided in the form of at leastthree substantially identical spaced apart members 29. Thus, for theillustrated cylindrical strap 21 and motor 10, a uniform gap ismaintained therebetween through the use of members 29.

In the arrangement illustrated in FIG. 1, six members 29 are utilized,three of which are hidden by the motor 10 in the drawing. However, asfew as three members 29 spaced apart approximately about the peripheryof the shell 14 could be used to establish a substantially uniform gapbetween the outer peripheral surface of the shell 14 and the internalsurface 28 of the strap 21.

Particularly when the adapter means are in the form of a member that isfabricated from a flat blank of strip material, it is desirable for theadapter means to include a plurality of legs. Moreover, when at leastthree legs are provided, the adapter means is preferably shaped so thatfirst and second legs are each jointed at one end to a third leg.Furthermore, the legs are arranged so that the third leg will span afirst peripheral surface portion of a dynamoelectric machine, and sothat at least one of the other legs will span a different peripheralsurface portion of the dynamoelectric machine. For ease of assembly withthe dynamoelectric machine, holding means that may be in the form of atleast two spaced apart depending elements are also preferably providedto secure, with a snap fit, the adapter means to the dynamoelectricmachine.

When the at least three legs of the adapter means are arranged on edgeas relatively thin, generally planar spacers to be compressed between amounting member and one or more dynamoelectric machine peripheralsurfaces that are spanned by one or more of the legs; the advantages ofa more stable arrangement may be obtained when stabilizing or stiffeningmeans are provided along at least a portion of one or more of the atleast three legs. In the preferred embodiments that will now bedescribed in more detail, it is convenient to provide such stabilizingor stiffening means by deforming at least a segment of one or more oftheat least three legs so that the segment is offset or otherwiseextends from the plane of the leg to which the segment is attached. Theoffset segment will then prevent buckling or bending of the leg that isreinforced thereby.

Inspection of FIG. 1 will reveal that the members 29, hereafter referredto as clips 29, are three legged generally U- or C-shaped structures.These clips are held in fixed relationship to the shell 14 of the motorby means of depending elements 33, 34, and 39, 41. The elements 39, 41include hooks or lips 31, 32 that hold the clips 29 to the shell 14 asillustrated. In the preferred exemplification, the elements 33, 34 snapfit against edge surfaces of the web 36 of the shell 14, it being notedthat the web 36 constitutes a first peripheral surface portion spannedby a leg 66 or bight portion of the clip 29. In-order to remove theclips 29 from the shell 14, it would be necessary todeflect the elements33, 34 in the openings 37, 38 so as to release the portion of the web 36that is trapped between the elements 33, 34. As revealed in the drawing,the elements 39, 41 are'disposed on either side of a web 42 whichseparates adjacent openings 43, 44 as shown in FIG. 1.

With the clips 29 fastened to the shell 14, the motor 10 and clips maybe readily positioned within the strap 21. Thereafter, the nut 26 andbolt 27 or other suitable clamping means may be used to tighten thestrap against the clips 29 and thereby transmit clamping or mountingforces to the housing of the motor 10.

In order to avoid mounting instability that could result from theseclamping forces and to provide an increased measure of reliability, theclips 24 each include stabilizing and stiffening means. These meanscomprise segments 46, 47 of the legs 48, 49 of the clips. These segmentsare of particular advantage in the case of clips 29 where the legs 48,49 are made from relatively thin strip material that could be bent orotherwise deformed asa result of the clamping forces applied theretowhen the legs 48, 49 are compressed between the shell 14 and the surface28 of the strap 21.

To illustrate one type of relatively thin strip material that may beused, clips 29 were made from approximately 0.050 of an inch thick coldrolled steel and then formed to the configuration shown in FIG. 1. Thesegments or offsets 46, 47provided resistance both to buckling,twisting, and shifting of the legs 48 and 49 relative to the motorshell. The segments 46, 47 imparted structural stability to the clips 29that would not otherwise have been obtained unless substantially thickeror wider strip material had been used to form the legs 48,49. v

The just described structural details of the clip 29 regarding the legs48, 49 and offsets formed therein are also applicable to the clip.51which has been shown in phantom in FIG. 1. However, the clip 51 isarranged to have depending elements 52, 53 formed at the bight portionthereof with both legs snapped into a single opening 54 in the shell 14.The elements 52, 53 are snapped against the edge surfaces 92 of twospaced apart webs 56, 57 as shown. In addition, the elements 58, 59connected to the free ends of the legs 63, 64 of clip 51 are disposedwithin one opening of the shell 14 and operate, in a manner similar tothe elements 39, 41 of clips 29 to prevent inadvertent removal of theclip 51 from the motor 10.

A more detailed description of the clips 29 and 51, shown respectivelyin FIGS. 2 and 4, will now be presented with reference also being madeto FIGS. 3 and 5 which illustrate blanks of strip material from whichthe clips 29 and 51 may be formed. The blanks shown in FIGS. 3 and 5were made from 0.050 of an inch thick cold rolled steel, although othersuitable materials could also be utilized. In addition, although theillustrated clips 29 and 51 were stamped and then formed, it will beunderstood that adapter means embodying the invention could bemanufactured by utilizing other manufacturing techniques. For example,adapter means could be formed from thermoplastic or thermosettingmaterials rather than metallic strip material.

The blanks 61 and 62 (see FIGS. 3 and 5) each had a width indicated bythe dimension W of about 0.480 of an inch. Furthermore, the height T ofthe indicated portions of the blanks was about 0.3 of an inch. Thedimensions S and R were selected relative to the nominal dimensions ofthe webs 36 and openings 16 of the motor shell 14 so that the elements33, 34 and 52, 54 would be fastened to the motor shell 14 with a snapfit.

For a motor shell having openings 16 formed therein of a nominalcircumferential extent of about 0.6 of an inch and webs 36 having anominal width of about 0.365 of an inch, the dimension S was selected tobe about 0.36 of an inch or less while the dimension R was selected tobeabout 0.605 of an inch or more. F urthermore, the overall length ofthe blanks 61 and 62 was selected so that, after the segments 46, 47, or71, 72 were formed in the legs thereof, the span U between the bightportions 66 and 67 of the clips and the bight portions of the hookedlegs 41, 59 was at least equal to or greater than the span D of theperipheral surface portion of the shell 14 to be spanned by the clips.Satisfactory results have been obtained when the span U of a clip 29 wasabout 1.8 of an inch and when the span D of the shell 14 was about .l%of an inch.

It will be understood, of course, that the unformed length of materialin the blanks 61 and 62 is sufficiently long to provide the desiredoverall span dimension U of the clips and-still permit formation of thesegments 46, 47 and 71, 72. Satisfactory results were obtained when thesegments 46, 47 were formed to have a radius of about $4 of an inch andhad a clearance therebetween of about 5 1 of an inch after the clipswere finally formed.

The clips 29 could be quite readily assembled with the shell 14 of themotor 10 by first inserting the elements 39, 41 into a pair of adjacentones of the openings 16, as designated at 43 and 44 in FIG. 2, with thelips or tabs 31, 32 of the legs positioned adjacent to the interiorsurface 81 of the shell 14. Because of the tapered configuration of thetabs 31, 32 the elements 39 and 41 were readily hooked onto the shell 14with the elements 33, 34 raised relative to and spaced from the web 36as revealed in FIG. 2. Thereafter, the clip 29 was pivoted about thepoint of engagement between the elements 39, 41 and shell 14 so as tomove the ele- .ments 33, 34 into snap-fitting engagement with the Asimilar assembly procedure may be followed when utilizing the clip 51shown in FIG. 4 although in this case, the elements 52 and 53 wouldfirst flex toward one another and then snap away from one another duringinsertion in an opening 16 in the shell 14.

It is noted, that of the two clips 29 and 51, the clip 29 would bepreferred in those instances where it is difficult to maintain accuratedimensions of the opening 16. This may be the case, for example, whenthe motor shell 14 is formed by stamping the openings 16 in a flat stripand then rolling the strip to form the cylindrical shell 14.

it should be understood that the foregoing detailed description has beenpresented only for purposes of exemplification. Thus, modifications maybe made in the selection of materials, step by step procedures andfabrication of the adapter means selected as well as dimensionalrelationships between various parts of a particular adapter means. Also,in some applications, it may be desirable to have the elements 33, 34 ofa clip 29 depend from the clip legs 48, 49 rather than from the bightportion or leg 66 as illustrated. Moreover, it may be desirable toprovide opposed pairs of elements 33, 34 at each end of one or both ofthe legs 48, 49.

With an arrangement as just described, the oppositely facing surfaces86,87 of pairs of elements 33, 34 would then snap into place across theedge surfaces 89 and 93 of openings at either end of a leg 48 and/or aleg 49 rather than the edge surfaces 92 as previously described.Furthermore, all of the depending elements may be similar to theelements 33, 34 and directed to snap across a span represented by web36; across a span with an extent of dimension D in FIG. 2; orcombinations'thereof.

The elements33 and 34, after being snapped into place, may be held undertension or compression by the edge surfaces of one or more slots 16 inwhich the elements 33,34 have been positioned. Also, as the roundedcamming surfaces or leading edges 86a, 87a or 52a, 53a of the clips 29or 51 respectively engage the shell 14, depending elements, e.g.,elements 33, 34 are stressed and deflected. Then however, uponcompletion of the insertion of the elements 33, 34, the elements 33, 34will spring back toward the initial unstressed condition thereof.Depending upon the thickness of the material in shell 14 and surfacecontours of elements 33 and 34, the elements 33, 34 may be held underslight tension even after being snapped into place. Of course, the samewould also be true of the elements 52, 53 which may or may not be heldin compression after final assembly. However, if elements 52, 53 are notcompressed in a shell opening 16, it is desirable for portions of theshell 14 to be trapped in the slots 96, 97 was to prevent theinadvertent removal of a clip 51 from the shell 14.

In view of the foregoing, it will be understood that the presentinvention is extremely versatile both in the fabrication and use ofembodiments thereof; and that preferred and alternate embodiments of theinvention capable of fulfilling the above stated objects have beendisclosed herein. Consequently, while in accordance with the PatentStatutes l have described what at present are considered to be preferredforms of my invention, it will be obvious to those skilled in the artthat numerous changes and modifications may be made therein withoutdeparting from the true spirit and scope of the invention, and it istherefore aimed in the following claims to cover all such modifications.
